This page is the latest incarnation of my official website. It’s a compendium of things I have published and other stuff I made during my spare time.

In this blog, I will keep track of the updates of this site. If you are interested, just subscribe to the RSS feed.

My new game is out: Silabitas
Tue, 12 Jul 2016 09:02:37 +0100
It's a word puzzle game, similar to the Japanese game "mojipittan". The main rule is that you can't place a new piece unless you create a word with it. It works well in Japanese because they only have a few syllables, but I think in English it would be very difficult to achieve. In Spanish, we have more syllables, but less than English, so I think I managed to reach a good compromise by mixing syllables with single letters. So it's a bit like Mojipittan plus Scrabble.

The word is localized to several languages, although the puzzles are always in Spanish. If you play in a language other than Spanish, there's access within the app to Google Translate so you can check the meaning of the words you've discovered. There's also access to their definition in Spanish through RAE online.

Some brief notes I took during the Eurographics Symposium on Rendering, last week in Dublin:

Swift Pixels: pixel art drawing app
Sat, 02 Apr 2016 11:02:54 +0100
I've spent last Easter finishing an app I had in mind. It's related to my previous post where I talked about Self-Organizing Maps. I used those maps to create the color palettes for the app, a simple pixel-art drawing app: Swift Pixels

The app is free. Enjoy

I've recovered some old Matlab code and turned it into a Javascript demo to show how SOM neural networks work. I used them in my thesis years ago to generate color palettes based in universal categories.

Here's the demo and more details: Color Experiments

May and Yam Against Pollution

I released a game for iOS and AppleTV last week: May and Yam Against Pollution.

It's a "re-imagining" of a game I made 23 years ago for the Amiga 500. I tried to keep the retro style, so I recovered some of the original sprites, and also tried to mimic the "copper lines" from the Amiga

If you try it, please let me know what you think (Twitter: @endavid)

I've refactored lots of this site so it's easier for me to maintain. Originally, I used a lot of static pages and PHP so people with old browsers could access it properly, but it was getting hard to maintain.

So I'm now making heavy use of Javascript. There are a few changes to make the page a little more dynamic, but otherwise it should look the same. I've only tested it on Chrome, Safari, and Safari for iOS. If you notice something is not working, please let me know.

Also, I've updated the list of works a bit.

Anyway, it's getting warmer, so let's go out and enjoy the spring!

Happy new year!
